DANIEL LAUER, OF -YORK, PENNSYLVANIA.

COMBINED SASH HOLDER AND FASTENER.

SPECIFICATION forming part of Letters Patent No. 596,889, dated January4, 1898. Application filed July 15, 1897. Serial No. 644,710. (Nomodel.)

To all whom it may concern.-

Be it known that I, DANIEL LAUER, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, haveinvented certain new and useful Improvements in a Combined Sash Holderand Look, of which the following is a specification.

My invention consists in a combined holder and lock which is simple andinexpensive in construction and effective in operation.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a front View of part of a window. sash and frame, partsbeing broken away to illustrate the lock. Fig. 2 is a face View of thesash-holder. Fig. 3 is a plan view, the frame being shown in section onthe line 3 3, Fig. 2. Fig. 4c is a sectional view taken on the line 44:, Fig. 3, showing the lock in op-,

erative position; and Fig. 5 is a similar View showing the holding-camin operative position.

In the drawings, A indicates the window: frame, B the sash, and G thecombined lock and latch. The parts of the lock and latch are mounted ina casting or frame to, consisting of a face-plate 1 and aninwardly-turned flange or box 2. The lock consists of a springbolt Z),which slides at right angles to the faceplate. The bolt has athumb-piece 3, a tongue 4, and a rearwardly-extending shank 5,aroundwhich is coiled a spring 6, tending to throw the bolt out. The rear endof the shank passes through and is guided in a hole in a yoke-piece 7,said yoke-piece, as shown, consisting of a piece of strap-iron rivetedto the frame. The bolt is prevented from passing through the hole by asmall too or projection on the rear end of the shank. The tongue of thebolt is rectangular, and it is adapted to engage rectangular notches 9in the windowsash, thus positively locking the sash.

The sash-holder comprises a roughened or toothed cam 10, which ispivotally mounted on a pin 11, connected with the box 2. The

cam is normally thrown out against the window-sash by a coiled spring12. Integral with the cam is a tailpiece 13 in the rear of the tongue 4of the bolt, as shown in Figs. 3 and 5, and the cam may be pressed in bypushinginward the thumb-piece of the bolt.

. My combined lock and latch are applied, as shown in Fig. 1, byattaching the same to the window-frame with the face flush with thesurface against which the sash runs. The sashes are provided withseveral notches 9, as many as may be desirable. One notch is providedfor locking the window in closed position, and others may be providedfor looking it open. The can], however, will hold it in any desired openposition. The cam and bolt may be said, in a sense, to workindependently, as they have independent springs, but the bolt is used towithdraw the cam to free the sash. The parts are so proportioned thatwhen both the cam and the bolt are pressed in and then released the camwill come out ahead of the bolt and the bolt will not therefore preventthe cam from engaging any part of the sash. The bolt upon being releasedwill simply spring against the sash if it is not opposite a notch.v If,however, it is opposite a notch, it will spring into the notch and lockthe sash rigidly.

What I claim, and desire to secure by Let ters Patent, is-

In a combined sash holder and lock, the combination with the framehaving a face-plate and flange, of a yoke 7 connected to the frame, asliding bolt having a shank extending through the yoke, a springsurrounding said shank, a tongue and a thumb-piece, a cam pivoted insaid frame, a spiral spring surrounding the pivot and normallythrowingthe cam out and the tailpiece integral with the cam, said tailpiecebeing in the rear of the bolt-tongue, whereby the withdrawal of the boltwill effect the withdrawal of the cam, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

I DANIEL LAUER.
